In Graphical Approach to a Simple Physics Problem and Regression Approach to a Simple Physics Problem I have discussed approaches to solving my daughter’s physics homework. Basically, the problem started with the following data, showing the time to drain water through a hole in a bucket, based on the diameter of the hole and the initial height of water in the bucket.

In the earlier two posts, I found that the drainage time was related to hole diameter through a power law relationship with an exponent of -2, and to height with an exponent of 1/2.
